Scheduling Rules not working in schedules created by Schedule Manager

Summary:

Hello,

We have a schedule generation profile where we have added a scheduling rules for Weekly Duration > 48h as below:
The cycle is 4 weeks in our schedule generation profile.

However when the schedule manager assign open shifts to employees from the float department, this rule is not applied.
There are employees who are assigned shifts (of 6h) 5 days or 6 days a week.

The employees have work pattern = Flexible days and times and they can work anyday of the week.

But the scheduling rule should apply and give a violation if the employee has been assigned more than for more than 48h in a week.
